Try to guess these 11 recommendations for harvesting invasive species

Models of population dynamics can be simple, like this logistic model,  but detailed models tailored to specific species and populations will be more successfull

Harvesting invasive species receives some scientific guidance, and perhaps a place manager’s toolboxes, this month with the publication of Pasko and Goldberg’s “Review of harvest incentives to control invasive species” (pre-pub proof) in the September issue of the scientific journal, Management of Biological Invasions.

Sometimes a net is mightier than a fork!

This post is a guest contribution from Sean Ryan and Meredeth Doellman of The Pieris Project. Read on to see how you can become involved with some exciting citizen science! Invasivore.org has had fun developing novel ways to engage the public with invasive species, but what do you do with those invasives that aren’t so …

Notes from the road: spotlights on leading plant invasive species research

Invasivore Sean Hoban recently attended the annual meeting of the Botanical Society of America in Boise, Idaho, which featured a session an afternoon session on some recent studies in plant Invasion Biology. Six researchers presented their latest ecological and genetic findings, from the interactive effects of Amur honeysuckle and white-tailed deer to hybridization among multiple …

Research spotlight: what triggers invasions?

A recent study utilized a thirty-year dataset to examine the question of how a reduction in the consumption of an invader might trigger an invasion.

Research spotlight: Rare natives hold out against invaders

The past few years have seen some serious discussion among conservation biologists about the biodiversity value of invaded communities.  For example, to what degree do some invasive species integrate into native communities, how extensive and permanent are the damages from invasives, and are native species able to evolve in response?  It is important to resolve …

When native species invade

White tailed deer is a species native to Kentucky, where I live, and to much of the eastern hardwood forest region of the USA.  However, white tailed deer have attained such high abundance that they cause major ecological problems normally associated with invasive species.  For example, white tailed deer browse tree seedlings, so in areas …

I recently subscribed to the Ecological Society of America’s podcast “Beyond the Frontier,” which features engaging interviews (usually 10 to 15 minutes, perfect timing for the walk to work) with scientists who have recently published in one of ESA’s journals.  One of my favorite episodes is an interview with Dr. Richard Shine at the University …

Climate change and invasive species are often listed as two of the greatest threats to biodiversity. Is it possible that changing climate can itself cause more frequent and damaging invasions, such that the two factors have synergistic effects?  A recent article in Frontiers in Ecology and the Environment by Jeffrey M. Diez et al. approaches this …

What future for plant invasions?

When it comes to invasives, three key words are prevention, prevention, and prevention.  We know that an efficient and strategic way to combat invasive species is to keep them from establishment in the first place, such as through quarantines, screening mechanisms, or black lists.  A useful question for such prevention policies is, “Which are the …

Invasive species? Better act local.

A recent study in the journal Biological Invasions, When are eradication campaigns successful? A test of commonly held assumptions, yielded some invasivore-friendly conclusions. Pluess et al. (2012) analyzed 136 eradication campaigns against 75 different species of invertebrates, plants, and plant pathogens to see what the successful campaigns had in common. The review examined several factors, …
